In late October, Petraeus personally traveled to Libya to investigate the CIA personnel who were in Benghazi on the night of the attack.
On the night Petraeus first announced his resignation, Krauthammer said the affair would spur the mainstream media to dig deeper into what transpired in Benghazi.
"It will now become the hottest story around and you can be sure that even the mainstream papers, which did not show any interest whatsoever in this story up to and into the election, are going to get on it," Krauthammer said. "It will unravel."
Implications that Petraeus was covering for the White House play into a larger theory floating around conservative circles that Obama administration officials like Petraeus and U.N. Ambassador Susan Rice purposely misled the American people following the attack in Benghazi.
Sens. Lindsey Graham, R-S.C., and John McCain, R-Ariz., told ABC's Jon Karl Wednesday that they would oppose Obama's hypothetical nomination of Rice to Secretary of State, with Graham saying he didn't "trust her."
President Obama responded to this opposition Wednesday at his first press conference since taking reelection, defending the U.N. ambassador.
"She made an appearance at the request of the White House in which she gave her best understanding of the intelligence that had been provided to her," Obama said. "If Sen. McCain and Sen. Graham and others want to go after somebody, they should go after me."
